NOTE:
13.0 REGISTER MAP
Registers are 32 bits (quadlet) wide and all accesses are always done on a quadlet basis. This means that it is not possible to write just the
and thus DON’T CARE.
A full bitmap of all registers is listed in Table 6. The meaning of shading and bit cell values is as follows:

A bit/field with no name written in it and dark shading is reserved and not used.
A bit/field with a name in it and light shading is a READ ONLY (status) bit/field.
A one bit value (0 or 1) written at the bottom of a writable (control) bit is the default value after power-on-reset.
